Ubisoft may be at work on an all-new game called Fighter Within.
Ubisoft announced last week that it would reveal an all-new next-generation IP during Gamescom later this month.
The company released a Kinect-exclusive fighting game called Fighters Uncaged in 2010.
Gamescom takes place August 21-25 in Cologne, Germany. In addition to the all-new game, Ubisoft's lineup for the show includes Watch Dogs, Assassin's Creed IV: Black Flag, Rayman Legends, and Splinter Cell: Blacklist.
Ubisoft is not the only major publisher making announcements for Gamescom. Blizzard Entertainment will make a "special announcement" during the show, while 2K Games plans to show off all-new XCOM content at the event.
